Tyler Resources Announces Further Drill Results at Bahuerachi, Including 50 Meters Grading 0.62% Copper and 1.01% Zinc in Oxide Mineralization in Diamond Drill Hole #26

CALGARY, ALBERTA--(CCNMatthews - June 9, 2005) - Tyler Resources Inc. (TSX:TYS) is pleased to announce assay results for diamond drill holes #26, 27 and 30 which outline continued mineralization to the south with near surface high grade copper oxide intersections from the Main Zone of its Bahuerachi project, Mexico. Results have identified near surface porphyry and skarn hosted oxide mineralization containing copper, gold, silver and zinc.



Significant intervals for drill holes DDH-BAH #26, 27, 30.

twinned with drill hole #30 to target depth and for which results
are reported.


Results from section 1 SE have outlined sections of near surface copper oxide mineralization with bulk mineable potential. Mineralization has been recognized along wide sections through surface sampling for an additional 300 meters further south at this time and further work is planned to prioritized favorable sections for drilling south of section 1 SE as the project continues. Two sections sampled at surface located approximately 300 meters south of section 1 SE returned assays of 0.4% copper, 0.12% zinc and 5.5 g/t silver over 46 meters and 0.11% copper, 0.5% zinc, 8.7 g/t silver over 50 meters in heavily oxidized calcareous sediments. Skarn mineralization at depth, while showing continuity, was found to be generally less well developed than on sections to the north and wide sections of poorly mineralized limestones and post mineral intrusions have diluted width potential in this area.

Drill hole RC-18, the last RC hole drilled by the previous RC contractor have been received and compiled on section 295N with previously released drill hole #19. RC-18 returned 97.53 meters grading 0.73% copper, 7.8 g/t silver and 0.34% zinc, including a high grade skarn section consisting of 18.29 meters grading 2.28% copper, 0.25 g/t gold, 31.35 g/t silver and 1.14% zinc.
